Frogs

Frenchmen, properly Parisians. So called from their
ancient heraldic device, which was three frogs or three toads. “
Qu'en disent les grenouilles? ”—What will the frogs (people of
Paris) say?—was in 1791 a common court phrase at Versailles. There
was a point in the pleasantry when Paris was a quagmire, called
Lutetia (mud-land) because, like frogs or toads, they lived in
mud, but now it is quite an anomaly. (See Crapaud.)
